Human IgG2-λ来源于人类骨髓瘤血浆；MDL number MFCD02662364 NACRES NA.46产品描述 General description IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections.[1] Human myeloma IgG2, λ is purified from human plasma by fractionation, ion-exchange and affinity chromatography procedures. IgG抗体亚型是免疫系统中最丰富的血清免疫球蛋白。它由B细胞分泌，存在于血液和细胞外液中，可防止细菌，真菌和病毒引起的感染。母体IgG通过胎盘转移到胎儿，这对新生儿抵抗感染的免疫防御至关重要。通过分离，离子交换和亲和色谱法从人血浆中纯化人骨髓瘤IgG2，λ。 Application The purified IgG2, λ may be used as an immunoglobulin calibrator, reference antigen, blocking agent or coating protein in a variety of immunoassays including ELISA, dot-blot immunobinding, Western immunoblotting, immunodiffusion, immunoelectrophoresis, hemagglutination, and cell-binding assays. Human myeloma IgG2, λ was used to check the efficiency of hydrophobic interaction membrane chromatography (HIMC).[2] Physical form Solution in 0.02 M Tris buffered saline, pH 8.0. Analysis Note The purity and identity are determined by immunoelectrophoresis, indirect ELISA, and SDS-PAGE.
